I have just downloaded CS6 and all of my apps are working except InDesign. I click to open, it launches, and then it crashes. I have reinstalled it, trashing the former install, and it still has the same issue. Tech support says this is the only way to get an answer, which I doubt, but am making the attempt anyway. Please help.

Considering that Photoshop and Illustrator are not InDesign your assessment is irrelevant. And given that you still haven't given us any details on what is happening or the operating system you're trying to run it on there's nothing anyone can do to help.

If you're on Windows 10 or any Mac OS later than 10.10, you're on your own.

We fixed it. There was a ghost file in the latest installation which we just removed. Trashed the former install, and installed again. Now it works! Just posting in case any one else has the same issue.
